15 Sec Comericial Radio

This is an idea that is kind of already in place if you listen to Pandora.  This would be a radio station that instead of running stints of music followed by long stints of commercial after commercial you would simply have a 15-30 sec commercial between each song.  That way your listeners would never be far enough away from the next song (time wise that is) that they don't change the channel when your advertising comes on.  It would be way more effective for customers that purchase advertising on the radio and the station would be a hit because, I think, people would appreciate the continuous flow of music.
